Summary of Changes

Hello @xushiwei, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the XGo ecosystem by introducing a dedicated Domain Query Language (DQL) for XGo Abstract Syntax Trees, enabling more flexible and powerful code analysis and manipulation. Concurrently, it refines the encoding packages by standardizing the primary data type returned by their New functions, promoting a more uniform and predictable API across different data formats.

Highlights

• New DQL for XGo AST: Introduced a new dql/xgo package that provides a powerful Domain Query Language (DQL) for querying and manipulating XGo Abstract Syntax Trees (ASTs). This includes Node and NodeSet types, along with methods for traversing, selecting, and extracting information from AST nodes.
• Standardized encoding.Object Type: Standardized the return type of New functions across various encoding packages (csv, golang, html, json, regexp, regexposix, xml, yaml) by introducing a consistent Object type alias. This improves consistency and clarity when working with encoded data.
• New encoding/xgo Package: Added a new encoding/xgo package, mirroring the encoding pattern, to provide a New function that parses XGo source code into an xgo.File object, leveraging the new dql/xgo parsing capabilities.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Code Review

This pull request introduces DQL support for the XGo language by adding new packages dql/xgo and encoding/xgo. It also refactors several encoding packages to use a consistent Object type alias, improving code uniformity. The implementation for XGo DQL follows the existing patterns for other languages like Go, and a helpful demo file is included. The changes are well-structured and clear. I have one minor suggestion to fix a typo in a panic message.
